Objective  To analyze the characteristics and changes of disease spectrum in bomber crewman hospitalized in our hospital, and provide evidences for aeromedical support and health management strategies for bomber crewman.

  Methods   Clinical data about bomber crewman hospitalized in our hospital from January 2013 to December 2018 and December 2006 to December 2012 were collected and the disease spectrum was analyzed and compared.

  Results   From 2013 to 2018, 435 cases were enrolled in our study, they were all males with average age of (36.1±10.7) years. The top five diseases in hospitalized bomber crewman were lumbar disc herniation (11.26%), followed by cervical spine disorder (10.34%), hyperlipemia (10.34%), hyperuricemia and gout (7.36%), and gonarthrosis (7.13%); and the top three systems invloved were musculoskeletal system (33.33%), endocrine system (26.44%), and gastrointestinal system (19.31%). From 2006 to 2012, 410 cases were enrolled in our study, they were all males with average age of (37.5±10.5) years. The top five diseases were cervical spine disorder (14.63%), lumbar disc herniation (12.20%), hyperlipemia (11.46%), chronic gastritis (10.24%) and liver dysfunction (9.27%), and the top three systems invloved were musculoskeletal system (37.81%), digestive system (29.02%), and endocrine system (15.37%). The proportion of endocrine and metabolic disease increased significantly whereas the proportion of digestive diseases decreased significantly over time.

  Conclusion   It is suggested that more attention should be paid to the prevention and control of orthopedic disorders, endocrine and metabolic disease in bomber crewman, and preventive measures should thus be taken to reduce cerebrovascular and metabolic risk factors.
